Flow patterns (42-month cumulative)

Inbound (numbers acquired)

Direct transfer from another RespOrg	49,638.0
Harvested from disconnect pool	23,649.0
First assigned from spare pool	108.0
Reactivated own disconnects	1,383.0

Direct transfer to another RespOrg	488.0
Standard disconnect aging process (3+ months in DISC)	0
Abbreviated disconnect period (1–2 months in DISC)	13,767
Released directly to spare pool	6,400.0

Of the 13,767 disconnect episodes this RespOrg has sent through aging, 100% were abbreviated (1–2 snapshots in DISC status). That's a strong early-disconnector signal, this RespOrg routinely releases numbers before the full 3–4 month aging window. Worth checking daily for vanity drops.

Summary

Their website uses flash which obviously isn't supported any more so they are probably so small they don't exist any more but I'll give them the benefit of the doubt and put them in the Small Phone Company category.
